Abstract

A planar first member 11 is split up into three or more conductive regions 13, 14, 15, 16, which are electrically insulated from each other. A second planar member 12 is insulated but capacitively coupled to the first member 11. Second member 12 may move over first member 11. An oscillator 25 generates two out-of-phase signals 26, 27 which can be selectively applied to different regions of the first member 11 by switch 31. The signal picked up by the second member is analyzed to give an indication of the relative positions of the two members. The use of the two waveforms allows the movement of the second member in two directions parallel to the plane of the first member to be sensed.
